Power Optimization and Management in Embedded Systems1


Introduction
A system consists of a set of components that provide a useful
behavior or service. System design is the process of
implementing the desired behavior or service while optimizing
some objectives and satisfying some constraints. For example,
a high-end desktop computer system is optimized for maximum
clock rate while meeting a price target. On the other hand, a
battery-operated portable electronic system for i ....etc
